Decatur Police and Texas Department of Public Safety troopers were posted at the entrances to Carson Elementary and Decatur High School Tuesday morning after both campuses were placed on lockdown due to a threat against a Carson employee. Police were alerted to the threat posted on Facebook and contacted DISD officials Tuesday morning. An automated call to parents with students at those campuses went out shortly after 8:30 a.m., and within a few minutes some parents were at the school to pick up their children. Superintendent Rod Townsend encouraged parents to “let us do our job,” noting that “security is the top priority here.” Townsend said both the employee and a child who is a student at the high school are in a safe location. The plan at this point is to keep the campuses under lockdown with heavy security until the suspect has been located. “We’re going to stay on lockdown until we know the safety and security of everyone’s children is not an issue.”
